How to paint? Introduction of color matching principle of coatings.

Paint is the material we will use when decorating. There are still many colors of paints on the market now, but there are still many colors that are not available, and many colors are based on color matching. Generally speaking, paint mixing is a technical activity that needs professionals to complete. However, amateurs can master skills through learning. So how do you color the paint? Let's share with you how to adjust the color of paint. I hope it will help you.

How to color paint —— Hint 1:

Before paint color matching, it is necessary to make a color matching sample, so as to determine how many secondary colors of paint are contained in the paint sample, calculate a color type participating in color matching, and then adjust the secondary colors and secondary colors respectively in a small container.

How to color paint-Tip 2:

In color matching, the main color paint is the most used, and only by adding color matching paint can you get the desired color. It is a colored pigment with a small amount of coloring. Add a secondary color paint with strong color power to the main color paint, stir it evenly, compare the samples and color samples from shallow to deep, and check at any time until satisfactory results are achieved. For example, if you use beige paint, you should first add a proper amount of white paint, slowly add yellow paint, and keep stirring until you reach the desired color.

How to color paint-Tip 3:

If you want to adjust the light-colored paint, but the paint may become darker after it dries, you should try it with a contrast sample first to see if the dried color is what you want. In color matching, you should grasp the floating performance of a primary color in advance, especially amino paint and perchloroethylene paint.

How to color paint-Tip 4:

In color matching, you can add an appropriate amount of additives, such as varnish curing agent and desiccant. If it is in cold winter, it is necessary to add desiccant to the container before starting color matching, so as not to affect color matching. Paint with the same performance should be selected when preparing colorful paint, and the solvent system should be compatible, otherwise the quality of paint will be affected, and delamination and gelation will occur in serious cases.

Introduction of color matching principle of coatings

Colors generally have different color heads, and so on according to the following principles:

1, when paired with positive green, yellow is generally used with green head and blue with yellow head;

2. When purple and red are matched, blue with red head and red with blue head should be adopted;

3. When matching orange, red with yellow head and yellow with red head should be adopted;

4. When preparing multi-color paints such as gray and green, a variety of pigments are needed. Various pigments have different oiliness and density, and often appear "floating color" and "blooming" phenomena. At this time, a small amount of surfactant, leveling agent and anti-floating agent can be added as appropriate to solve the problem, and the addition amount is generally 0. 1% ~ 1%.

The above is the introduction of how to adjust the paint color and the principle of paint color matching. After reading it, you can try to color the paint, but when choosing the paint, you must choose the paint of the same brand, otherwise it is likely that different brands and different raw materials will have chemical reactions when mixing the paint, resulting in the inability to adjust the color we want.
